Abstract (en)

[origin: US2021226305A1] An electrode assembly, including a first electrode plate, a second electrode plate, and a separator. The electrode assembly is formed by winding the first electrode plate, the separator, and the second electrode plate. A first tab formed by a plurality of first tab units and a second tab formed by a plurality of second tab units are disposed on the first electrode plate, and a third tab formed by a plurality of third tab units is disposed on the second electrode plate. The electrode assembly is provided with a multi-tab structure to achieve purposes of enhancing a current-carrying capacity of the battery and reducing a temperature rise.
